GENERAL DESCRIPTION
The Z86E03/E06 are One-Time Programmable (OTP)
members of the Z8
®
microcontroller family allowing easy
software development, debug, and prototyping for small
production runs that are not economically desirable with a
masked ROM version.
Three address spaces, the Program Memory, Register
File, and Expanded Register File (ERF), support a wide
range of memory configurations. Through the ERF, the
designer has access to four additional control registers
that provide extra peripheral devices, I/O ports, register
addresses, an SPI receive buffer and SPI compare
register.
For applications demanding powerful I/O capabilities, the
Z86E03/E06's dedicated input and output lines are grouped
into two ports, and are configurable under software control
to provide timing, status signals, or parallel I/O.
Notes:
All Signals with a preceding front slash, "/", are active Low, e.g.:
B//W (WORD is active Low); /B/W (BYTE is active Low, only).
